Specification of Letters Patent.

lPatented Nov. 10, `1914.

To all whom it may concern:

Be it known that I, VITO NUNzro ROSATO, a citizen of the United States, and a resident of Yonkers, in the county of Westchester and State of New York, have invented a new and Improved Aeroplane, of which the following is a full, clear, and exact description.

This invention relates to aeroplanes and has particular reference to the construction thereof with respect to increasing stability and safety. Y

More specifically stated, I provide an aeroplane body having longitudinally larranged passageways for air, and such passageways are controlled by certain pivoted doors or shutters for the purpose of increasing the safety of the device in case of accident.

A further object of the invention is to provide an upwardly inclined passageway through the aeroplane' body and mount therein a wheel having geared connections with an auxiliary propeller for the purpose of steadying the machine in ordinary flight.

The foregoing and other objects of the invention will hereinafter be more fully described and claimed and illustrated in the drawings forming a part of this specification in which like characters of reference indicate corresponding parts in all the views, and in which- Y Figure 1 is a plan View, partly broken away, of a preferred form of this invention; Fig. 2 is a side elevation of the same; Fig. 3 is a longitudinal section on the line 3-3 of Fig. 1; Fig. 4 is a diagram indicating the movable controlling devices. Fig. 5 is a front elevation of the machine; and Fig. 6

is a perspective view ofthe front axle construction.

The several parts of the-device may be made of any suitable materials, and the relative sizes and proportions of the same may be modified to a considerable extent without departing from the spirit of the invention hereinafter more fully set forth and speci- -cally claimed.

ASv shown, the machine is preferably of the biplane type comprising the two main planes 10 and 11 extending transversely and one above the other, as is usual in vmachines of this type. I also provide auxiliar planes 12 and 13 which. are smaller than. emain planes and are arranged at the rear end of the machine. I also provide -stabilizing planes which extend from the main to the auxiliary planes and preferably parallel to the longitudinal axis of the machine.

The body 15 of the device is somewhat in the nature of a boat, having its front end tapered as shown at 15. The main plane 10 extends laterally from the body 15 in both directions. .The body 15 is provided with an opening llbetween the two planes 1() and 11 and there is a current of air directed through said opening between the planes under ordinary conditions. The passageway for this current of air is restricted on the sides by means of walls 17 and 18 connectlng the main planes aforesaid. The body 15 is provided also with an opening 19 in its bottom which communicates with an inclined upwardly directed wind passageway 2O bounded on the rear by a wall 21 and on its sides by walls 22 and 23.

At the rear portion of the machine there is provided an auxiliary wind passageway 24C bounded on the bottom and top by the planes 12 and 13 respectively, and on its sides by the walls 25 and 26. The front wind passageway is adapted to be more or less closed by operation of a shutter 27 mounted on a horizontal pivot 28 and controlled by means of fiexible connections 29 leading to a hand lever 30 within convenient reach of the aviator on the seat 31. The current of wind leading to the passageway 2O is controlled in its direction and' course by means of a wall 32 constituting a part of the body 15. Said current of air is guided also by a fixed wall 36 extending across the front portion of the passageway 20. A wheel 37 is journaled on a transverse pivot within said passageway 20 and is adapted to be driven by the current of air passing through the passageway 20, as indicated in Fig. 3.

The main propelling devices include a motor 38 having connections by suitable shafts and gearing to a set of three propellers 39 and 40. The propeller 39 is mounted at the point or nose of the machine, and the other two are located on either side of the `body 15 and in front of the main planes. The wheel 37, as indicated, serves as an auxiliary propelling means and has suitable gearing shown at 41 leading to an auxiliary propeller 4.2 just in front of the auxiliary planes 12 and 13. The primary purpose of this Apropeller' 42 is to steady the machine in its flight. The current. of air passing through the passageway 24 is conl made vof peculiar form,'being substantially l for their several purposes.

. as possible in will have wedge-shaped and is comparatively wide at its rear end, as shown in Figs. 1 and 4. IThe rudder as well as the other main portions of the device will be made hollow and as light proportion to the required strength. c

Supporting wheels 53 and 54 are provided on front and rear axles 53 and 54 respectively, and these wheels and axles are supported by means of yokes 55 having suitable connection with a hand lever 56 whereby said yokes and wheels may be thrown upwardly toward the body 15 so as to bring the wheels on opposite sides thereof. Each pair of wheels is permitted to occupy the position indicated by virtue of an arched formation of the axle to which thewheels are connected. l

The operation of the device may be briefly ldescribed as follows: The wheels 53 and 54 support the machine ywhile it is on the ground and assist the starting thereof in the usual way. After the machine leaves the ground, lthe wheels are preferably elevated as above referred to. The-main and auxiliary propellers cause i iliary planes to .lift the machine and the stabilizing and steeringdevices are'operated The machine, if descending, while in normal horizontal position, will receive an air current through the opening 19 which acted upon the wheel 19 and inally'pon the auxiliary propeller 42, a tendency to vmake the machine glide and hence increase the safety of the machine. lIt will be noted, furthermore, that when the shutters 27 and 43 are closed, they will act in the nature of a brake or means` to retard the speed of the machine while gliding through the air. They'also act to direct the machine upwardly or downwardly.

The body 15 being somewhat boat-shaped 1s well adapted to be supported upon the shutter 33 may e operated 4by connections 34jjand a lever 35 to quickly close the open- I' ing 19, keeping the water out of the passages way 20. y

Having-thus described, myyinvention, I l

the main and aux of water. lAt such time a l. In an aeroplane, the combination vof a central longitudinal' substantially boatshaped body, a main plane extending laterally on each side of said body, another main plane above the rst mentioned plane and vertical partitions providing ya`longitudinal central air space, propelling and steering means for the machine, a portion of the propellin means including a power wheel acted upon iyfa current` of air passing through said air space, means to control the current of air therethrough, an auxiliary plane in the rear ofv and parallel to the main plane, and stabilizing planes 14 on opposite sides of the body extending between the main and auxiliary planes and providing a large censpace. f

In an aeroplane, the combination of a longitudinally arranged boat-like body having a central opening through its bottom, main. propelling and steering devices, an air passageway. extending upwardly and rearwardly from said opening, means to control the passage of air through said passgeway, `a power wheel journaled on a horizontal axis in said passageway substantially closingthe same, an auxiliary propeller, and

lgearing extending between said wheel and said auxiliary propeller. 4. In an aeroplane, the combination of lifting planes, stabilizing planes arranged in fixed position in longitudinalA parallel rela tion and connected with said lifting. planes, a pair of movable stabilizing planes at the front of the machine, a vertically arranged rudder at the rear end of the machine, said rudder being substantially ,wedge-shaped, 'and a serie's of independent levers within reachof the aviator for the` control of said movable operating devices.
